This solution is more succinct and it works in the sablotron
configuration I have currently. I see why the parenthesis are necessary,
to keep referencing the movie nodes at a global level.
Thank you for your help!

Your problem is that in your code you have expressions like this:
//movie[position() <= number($thisMany)]
When actually you want this expression instead:
(//movie)[position() <= number($thisMany)]
Investigate this problem (e.g. look into the XSL FAQ) and try to
understand the difference between the two XPath expressions. This is a
FAQ about using the abbreviation //
So, you have to make just two changes in your code:
1. Change:
> <xsl:for-each select="//movie[position() <=
> number($thisMany)]">
to:
<xsl:for-each select="(//movie) [position() <=
number($thisMany)]">
2. Change:
> <xsl:for-each select="//*[name()='movie'][position() >
> number($thisMany)]">
to:
<xsl:for-each select="(//*[name()='movie']) [position() >
number($thisMany)]">
The corrected code now produces a nice 2-column table.
